I have the lenovo y510p and I was wanting to know how to change or upgrade the graphics card. Right now I have the GeForce gt 750m w/ 2gb. My laptop has the ultrabay so I can take the one of the graphics card out and put in a cd rom. I heard that you could put in a better graphics card but only in the family of the graphic card. Since I have the GeForce gt 750m I wanted to change it to the highest graphic card in its family wich is the GeForce GTX 780m. Here is the link for the graphics card and its family.

So would I be able to buy a better graphics card and replace it?
